And you actually recall that!?! Do keep in mind that I was not all there at that time...

I wrote the supidest answer of my life.

It's like the best of : " 3 I have to resist the urge to post "Have you considered a tinfoil hat?" - 9h ago by "

ACuriousMind

The star wall? Oh yes, it's intended to be a "best of"

And you, too, can star things! ;)

G. Bergeron

Was I rude when I answered to Maks? He seemed to just have went away...

I would have given this and the post about TBBT billions of stars

...well the post about the post about TBBT

ACuriousMind

@G.Bergeron Mhh, well, I think he noticed we were talking about other things and went away after you couldn't immediately help him

G. Bergeron

BUt:
... ummm well you know if you blow water in the pipe, water will rise, yes. But the sucking will not perpetuate itself

@G.Bergeron Hover with your mouse over the message you want to star, then click on the little star to the right. You can do it regardless of how old the message is

@ACuriousMind I've read Norton; while I don't love his writing style or his concept of generative capacity, I am very allured by his "cause as folk science"; it was a good read :)

G. Bergeron

By the way... would anybody know out of their head to second deRham cohomology group of a 4-sphere?

G. Bergeron

Yes

True, you dabbled in algebraic topology, no?

ACuriousMind

I think my profile says I dabble in algebraic geometry, but yeah, I can do topology, too ;)

G. Bergeron

I am not much into known territory there but it is coming

Actually, I never did an actual topology class. It's like the missing founding block of my math curriculum...

ACuriousMind

00:10

Well, what is "actual topology" anyway?

G. Bergeron

Like a class with the word topology in it

The class is actual not the topology

ACuriousMind

E.g you won't need all those $T_i$-separation axioms "true" topologists care about for most applications of "topology"

@G.Bergeron Ah, well, I took "algebraic topology", but it sorta assumed you know basic topology already

G. Bergeron

Yeah but at the same time a lack some common reflexes and facts and at the beginning of every graduate classes there is a bit of confusion and a lot of work involved until the topology gets out of the way :p

Soooo... I think I need to take that graduate algebraic topology class next semester just to end this game

I am making myself to biased towards pure algebra...

well... see you guys

ACuriousMind

I needed to come back to tell @BernardMeurer I just got the best idea: watching ARRIVAL !!! 8D

Y'know, I wasn't such a fan of that movie

Q: How to compute entropy of networks? (Boltzmann microstates and Shannon entropy)

I also asked in SO here a few days ago, thought it may be also interesting for physics-related answers. I would like to model a network as a system. A particular topology (configuration of edges between vertices) is a state-of-order of the system (a micro-state). I am trying to compute the entr...

Thoughts about what, if anything, the mods should do about that? It's a crosspost from SO, but that could be okay (crossposting is okay if the question is on topic for each site and it's acknowledged)

Bernard Meurer

00:42

@G.Bergeron Oh god

@DavidZ I absolutely hated the movie

ACuriousMind

> The best thing to do is to call in dino-hitler! (I had to answer one of these with a joke answer, sorry it was this one, eh?)

wat

DanielSank

01:21

@BernardMeurer Meh. It was ok.

I felt like half of the plot didn't matter, but the other half was interesting.

Bernard Meurer

@DanielSank Why would they hire a theoretical physicists to decipher an alien language?

And the line "I've had my head tilted at the stars ever since I can remember, but it wasn't meeting them [aliens] that amazed me the most ... it was meeting you"

WAS HORRIBLE

CRINGE

Skyler

01:40

@DanielSank hey

do you ever toss fresh tomatoes into your chilli?

Bernard Meurer

@Skyler Do you have the link to his "Famous Chilli" recipe?

ACuriousMind

Dec 2 at 9:26, by DanielSank

@BalarkaSen Are you familiar with my world famous chili?

Skyler

dam acm that was fast

Bernard Meurer

Jesus ACM

ACuriousMind

B)

Bernard Meurer

01:44

I'm still in love btw

Skyler

Oh great, I have a massive bag of tomatoes I need to finish before going to LA @DanielSank so I can bring that too

btw, thought you guys might havve a good laugh, heather dont click this if you read later youtube.com/watch?v=b8AX7QN68bw

DanielSank

02:00

@Skyler Worst derivation ever.

Use algebra, scrub.

@BernardMeurer With me, right?

Right?

dmckee

According to one of my undergrad professors $\xi$ is pronounced "more squiggle".

Skyler

@DanielSank ikr, i remember seeing that in griffiths and annotating my book with an arrow saying loser to that section

dmckee

Just plain "squiggle" is \eta.

Bernard Meurer

@DanielSank We have a platonic thing :P

Skyler

@dmckee sounds about right

DanielSank

02:02

@BernardMeurer Who, you and I?

Skyler

@DanielSank It was love at first sight, even though you haven't seen Bernard yet #stalkingisfun

DanielSank

@Skyler dafuq? I've met him in person twice.

David Z

@dmckee I would have thought $\zeta$ would be just "squiggle"

Bernard Meurer

I have an ideal, platonic love with Daniel, a functional, practical love with my neighbour and a strong attraction to every other woman who shows mild interest

Skyler

@DanielSank wait really

Bernard Meurer

02:03

@DanielSank Yes

Skyler

when was he here?

DanielSank

DO NOT DOUBT MY ABILITY TO MEET EVERYONE ON PSE

dmckee

@DavidZ I think that's right. Been a while.

Bernard Meurer

@Skyler I went to his wedding

DanielSank

^

Skyler

02:03

@BernardMeurer were you close by or something?

feeling bro jealousy here

Bernard Meurer

@Skyler Nope, I was in Brazil

I just joked about crashing it

and he joked about inviting me

so I joked about going

and then I went lol

Skyler

@BernardMeurer ...lol

DanielSank

Quick, someone: what's the default column width for a LaTeX article in two-column mode?

Skyler

@DanielSank too damn small

Bernard Meurer

@Skyler That's actually a true story

dmckee

02:05

@DanielSank Eh? revtex4_1 know that, so I don't.

DanielSank

@dmckee Nah, screw revtex

Skyler

@BernardMeurer how far did you have to go?

Bernard Meurer

@Skyler From Rio, Brazil to San Diego, California

Skyler

@BernardMeurer damn, aren't you just like entering college

how mucch did that flight cost

Bernard Meurer

@Skyler Yeah I'm an undergrad

Really cheap

I don't recall how much, but it wasn't an expensive flight

then I stayed for free in LA at the house of the sister of another PSE member

and took the train to SD

Where a friend of a friend has an airbnb that I stayed in for extra cheap

Skyler

02:09

@BernardMeurer youre going to be a successful man in the future going by your networking skills

Bernard Meurer

@Skyler Thanks, that's nice of you to say

To be honest I just want to kill JavaScript though

Skyler

@BernardMeurer where did you end up going btw?

@BernardMeurer harharhar

Bernard Meurer

Going where?

Skyler

@BernardMeurer university

Bernard Meurer

Ah, in an unfortunate turn of events I ended up at the university of lisbon, in portugal

I'm trying to transfer

I'm going insane

ACuriousMind

02:13

@BernardMeurer You were never sane.

Bernard Meurer

@ACuriousMind Well, yes, but I was happily insane before; now it just sucks

Skyler

@BernardMeurer whats bad about there?

@BernardMeurer i thought you got in somewhere up here

the rent wasnt as cheap as the flights?

Bernard Meurer

The tuition was too expensive, I had some familiar problems that screwed things up too

I got into some good schools

All my courses apart from linear algebra and analysis suck :)

Also the methodology is super backwards

ACuriousMind

@dmckee You're at least consistent in remembering it was eta ;)

Aug 12 '14 at 3:49, by dmckee

@alemi I had a prof who used "squiggle" for eta and "more squiggle" for a lower case zeta. We could necver decide if he was putting us on or not...

Skyler

02:29

@BernardMeurer ive heard about brazillian schools from a friend who goes to UFPR, i feel for you

Bernard Meurer

I don't go to a Brazilian school, I go to university in Portugal, in Europe

Hiro

Hello, I have a question regarding crystal field theory, why does the crystal field splitting energy increase down a group with the same oxidation state in a complex?

Skyler

@BernardMeurer oh ok, im derped

read that as being a Portuguese uni

not in portugal

Hiro

Since the atomic radius increases down a group, doesn't that mean that the d orbitals are going to be farther away from the center, does that cause a greater electronic repulsion with respect to the ligands in the complex, and is that what causes an increase in the crystal field splitting energy???

Bernard Meurer

Portuguese == in Portugal, no?

Skyler

02:54

@BernardMeurer well i was thinking more language than location

brain reading skippy thingy, you know what i mean

@DanielSank so about the ton of tomatoes... sound like it could help with the chilly?

Bernard Meurer

I do, I do, I'm just not following the commandments of my shirt

DanielSank

@Skyler Absolutely yes.

It's way better with fresh 'matoes.

Waiting to hear from Jason.

@Skyler where'd you get fresh tomatoes anyway?

ACuriousMind

...are fresh tomatoes some sort of rarity in the US? oO

DanielSank

@ACuriousMind In the middle of winter I'd venture that they're a rarity everywhere.

If you're eating fresh tomatoes in winter then either they're gross-ass mealy half-white tomatoes with absolutely no aroma or flavor whatsoever...

Bernard Meurer

03:10

Not in Brazil...

DanielSank

or you have magic powers, which is why I'm intrigued.

Bernard Meurer

We have beat the evil Winter

ACuriousMind

I'm reasonably sure we have fresh tomatoes year round here, though I have no idea whether from greenhouses or imports..

Bernard Meurer

Killed it

DanielSank

@ACuriousMind If they're not disgusting, then I'm thoroughly impressed with German science.

ACuriousMind

03:10

And the cheap ones don't have much flavour, yeah, but that's no different in the summer, either :P

DanielSank

@ACuriousMind Can you get good ones for more $$ in summer?

@BernardMeurer I need help.

Bernard Meurer

@DanielSank Also, I was there in the winter, it was warm as hell idk what you're up to talking like you'll freeze the tomatoes or something

@DanielSank What's up?

DanielSank

I'm working on some documents in my theory repo. There is some amount of cross-importing, i.e. certain documents import others as sub-parts.

LaTeX has this thing where you can label equations etc. How should i organize the equation labels so as to avoid name collisions?

ACuriousMind

@DanielSank I'm also reasonably certain I can buy good ones for money now

DanielSank

@ACuriousMind Devilry! It cannot be.

Send photo of Greek person eating tomato with smile as proof.

ACuriousMind

03:13

...why Greek? oO

DanielSank

Because in Greece they have legit tomatoes.

ACuriousMind

Where am I supposed to get a Greek person from all of a sudden? :D

DanielSank

I thought, my entire life, that I disliked tomatoes... until I was in Athens.

Bernard Meurer

@DanielSank Ask for it to be his cute ass friend eating a tomato

ACuriousMind

@BernardMeurer Dude, stop being creepy :P

DanielSank

03:14

I was standing on a street corner, and was struck by a wonderful aroma. I followed it around the corner to a produce shop.

Turned out I like tomatoes if they're good.

Bernard Meurer

@DanielSank Hm, I'm not sure about that, you want a naming-scheme?

ACuriousMind

Alas, I will go buy tomatoes tomorrow to test it

Bernard Meurer

@ACuriousMind It's stronger than me

DanielSank

@BernardMeurer yup

The labels all go into a global namespace, which sucks.

I think maybe I need to have local and global names... like, within a file, there can be names prefixed local which are not allowed to be referenced elsewhere.

or something.

@ACuriousMind suggestions?

David Z

@DanielSank I use colons as section separators, e.g. eq:cross section:leading order

Bernard Meurer

03:15

does SECTION-[SUBSTRUCTURE{Theorem,Proof,...}].NAME seem okay?

ACuriousMind

@DanielSank How are you naming your equations that they can collide? oO

DanielSank

@DavidZ :34004748 I don't particularly want to use the section names, but maybe that's a good compromise.

@ACuriousMind You're really working that "oO" today, eh?

@ACuriousMind It's less about collisions as about the names being meaningful and helping me find their original definition.

David Z

@DanielSank of course you don't have to use the section names - just use whatever name correlates to the organizational unit you want

DanielSank

I suppose.

Bernard Meurer

the [] around the SUBSTRUCTURE part are meant to mean it's optional, like in manpages

David Z

03:18

That idea about having names prefixed local which can't be referenced elsewhere seems like it could get tricky, unless you make the compiler enforce it

ACuriousMind

@DanielSank Well, I usually just use eq:WhatTheEquationDoes, never had a problem with that, although the identifiers can get rather long.

DanielSank

@DavidZ We do that in python all the time though; we prefix with _ to mean "don't use this from outside this module/class, and if you do, and it changes, too bad for you".

@ACuriousMind I see.

David Z

@DanielSank Of course, I'm familiar with that

Plus there are packages and modules and classes which are their own organizational units

dmckee

The old hank for c-libraries was to prefix all exported symbols with a 3iish letter identifier for the source.

DanielSank

@dmckee "Old hank". I like that phrase.

dmckee

03:23

er ... that was suppose to be "hack", but I've been typing all day and I'm tired.

DanielSank

@dmckee :D

Ok, colon separated list it is.
